do you have some specific examples? (not a rails user, so if there are obvious things, i'm unware)
a bit ot, but i've noticed an uptick in what seems like a reductive/straw-man characterization of disagreeing with particular ideas as summarily dismissing "different ideas" in general.
Rails is an opinionated framework in that it has strong opinions for what the default configuration should be. They realise it can't be general purpose and stay as effective. But if you're doing CRUD apps, on the web, those defaults save you a bunch of time.
That's not hostile to differing ideas, it's just saying that some ideas don't belong in rails or rails itself becomes less good.
